Basic Alchemical Information:

1)  All items, no matter if they are bound, or non-bound items, must be "Attuned" on an Eldritch Altar if you want to perform any of the Eldritch Ritual listed below.  Attuning an item, effectively Binds it to you, if it wasn't bound already.  This prevents you from being able to trade the item.

2)  Attuning an item requires (minimum level of item ^ 2) Khyber Dragonshard Fragments, so a minimum level 12 item would require 144 fragments.

3)  There is more than just the Alchemical Crafting rituals, you can also use Khyber, or Siberys Dragonshards, and Dragonshard Fragments on the Stone of Change to combine them into larger versions. For example, 10 Flawed Siberys Dragonshards can be combined to form an Imperfect Siberys Dragonshard, or 1,000 Khyber Dragonshard Fragments can be combined to form 10 Tiny Khyber Dragonshards, suitable for low level castings of Trap the Soul.

4)  You can only ever have 1 Ritual on an item/weapon/armor at a time.  If you have the Force Damage on a weapon, and you go to put the Force Critical on it, the Force Damage would disappear to be replaced by the Force Critical.

5)  I'm not even going to get into any detail about the "Adamantine Ritual", as it has become completely obsolete and is much more trouble than it is worth to obtain it.
